STATIONARY ELECTRIC-IRON HEATER.

To all whom it may concern:

Be it known that I, ABRAHAM S. ISERSON', a citizen of the United States, and a resident of the city of New York borough ofManhattan, in the county and State of New York,

have invented a new and Improved Stationary Electric-Iron Heater, of which the following is a full, clear, and exact description. This invention relates to electric flat irons and has particular reference to means to facilitate the use ofsuch irons.

Among the objects of the invention, there- I fore, is to provide an electric connection for a fiat iron which will be independent of the iron when the iron is in actual use for laundrying purposes, thereby making the iron free and inde endent from all mechanical obstructions w ich tend to interfere with the free use thereof.

Another object of the invention is to provide a stationary support to receive the iron while it is being heated, said support co'nstituting the means to which t e electric wires are attached and also being provided with suitable contacts to bring the iron heater into action when the iron is supported upon the support substantially the same as if the electrlc wires were connected directly and permanently to the iron.

A further object of the invention is to provide a safety switch within the support so arranged as to be automatically thrown out to break the circuit through the exposed contacts when the iron is lifted from the support, but which is complete the circuit by t e physical contact of the iron when the iron'is returned to the support for reheating. 1

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a ractical embodiment thereof reference is liad to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a vertical central longitudinal section on the line 11 of Fig. 2; a

Fig. 2 is a plan view;

Fig. 3 1s a view similar to Fig. 1, but. with Specification of Letters Patent.

Application filed September 9, 1916. Serial No. 119,217.

the iron removed and the automatic switch thrown to its opposite position; Fig. 4 is a vertical transverse section on theline H of Fig. 3; and

Fig. 5 is a diagram indicating the electric clrcult and its connections.

Referring now morev particularly to the drawings, I show a flat iron support 10 of any suitable size or design and comprisin a fiattop 11 of slate, soapstone or any otl er suitable material upon which the smooth bottom surface of the flat iron 12 is adapted to rest while the iron is being heated. The slab 11 is built upon a base 13 of suitable structure providing for a hollow center 14, in-which the electric connections or controlling devices are mounted, and access to which may be had through the open bottom of the base. It ,will be understood that the support 10 may be of sufiicient-weight to maintain it in suitable position at any convenient place adjacent the operators table or ironmg board, which said support maybe anchored in any suitable manner to the table or other point of support, but which support may be regarded as stationary in the practical operation of the invention.

The iron is or may be substantially similar to electric irons as now commonly found on the market, but for the purpose of the present disclosure, I show the flat iron comprising a heat retaining base 15, in connection with which is provided a rheostat or heater 16 having opposite terminals 17 i and 18 for the electric connections.

In accordance with the usual practice of electric irons, the feed wires 19 and 20 are run into the body of the iron and permanently' secured to the contacts 17 and 18. Under these circumstances, the wires must necessarily follow the movements of the iron and cause much inconvenience and annoyance to the user of the iron.

In accordance with my invention, the feed wires are connected permanently to or in commodation of fiat irons ofv slightly different lengths and also insures that proper engagement will be made between the heater contacts 17 and 18 carried by the iron and the spring contacts 22 and'23 with which said heater contacts are adapted to engage respectively when the iron is supported upon the slab for the purpose of being heated.

So far as the invention is now described, it will be seen that when the iron is placed upon the support, resting; longitudinally between the contacts 22 and 23 at one end and the Vshaped guard 26 at the other end and supported also from lateral displacement by corner brackets 27, the feed wires 19 and will be electrically connected through the heater 16- with precisely the same eifect upon the heater as though the 'the heat inthe base 15 for a considerable feed wires were connected directly and permanently to said heater. Furthermore,

when the iron is heated and lifted from its support, the circuitw'ill be broken between the feed wires at the contacts 22 and 23. The iron will thus be free for such manipulation as it is intended for and will retain used, but with none of their disadvantages.

In other words, the iron according to this invention is used substantially the same as though it were being heated upon a hot stove or the like, being entirely free for manipulation when lifted from the stationary support.

The guard 24 extending well over the contacts 22 and 23 makes it reasonably safe for the operator against receiving a shock, but I prefer to use an automatic switch, as indicated at 28, within the cavity 14: of the support. Said switch is shown as of a knife blade type pivoted at 29 and acted upon by a spring 30 tending to throw the switch blade out of contact with the spring contacts 31 connected respectively to the feed wires. A pin'32 projects vertically through a hole 33 in-the slab 11 and bears at its inner end upon the opposite end 28 of the switch blade. that when the iron is placed upon the slab, the pin will be forced downwardly causing the switch blade 28 to come between the con-- tacts 31 and close the circuit at this point, theweight of the iron being suiiicient for this purpose. Hence, so long as the iron remains in its heating position, the circuit The length of the pin 32 is such tarmac will be completed through the contacts 31, as well as through the contacts 22 and 23. When, however, the iron is lifted, the spring 30 breaks the contact at the points 31 and thus the then exposed contacts 22 and 23 become dead and thoroughly safe from'any likelihood of shocking'the operator.

I indicate at 34:, a fuse which may be used, if desired, to prevent the danger of short circuiting and I also indicate at 35 a manually operated switch for turning on or of? the circuit for the convenience of the operator. This switch 35 also constitutes an indicator whereby the operator will always know at a glance whether the current is on or oil. Under those'circumstances when the iron would otherwise become too hot while supported in heating position, it may be rested on any other support or placed transversely of the slab 11 out of contact with the contact springs 22 and 23.

In this position, even though the pin 32 is depressed, the circuit remains broken at the spring contacts. I claim? 1. The herein described electric iron support comprising a stationary base to directly receive and support the iron, a pair of feed wires extending into and upwardly through the base, a pair of contactsfor the respective wlres, a guard extending over said contacts to protect the operator, said contacts being secured to the guard, and flexible means connecting the guard and the contacts to the support base.

2. The herein described electric iron support comprising a stationary base, a pair of feed wires extending upwardly through the base adjacent one end thereof, a pair of contacts connected to the ends of the wires, a guard extending beneath and over the contacts, ,the contacts being rigidly secured to the lower portion of the guard, a fixed guard at the other end of the base, and resilient hinge means connecting the first mentioned guard'to the base providing for a slight variation in distance between the two guards according to the various lengths of irons used in connection with the support.

3. In an electric iron support, the combination ofra rigid base having a fiat horizontal upper surface upon which an iron is adapted to be placed by direct downward movement, a fixed guard for one end of the iron, a resiliently supported guard for the other end of the'iron, a pair of contacts fixed to one of said guards, a pair of circuit wires leading to said contacts, a movable switch below the horizontal supporting base, means acting upon the switch tending to break the circuit through said wires, and a vertically reciprocating pin movable through the central portion of the base and depressible by the weight of the iron when the iron is lowered into sup orted position to move the switch to closed position.

4. The herein described electric iron support comprising a stationary base, a pair of spring contacts carried by the base, feed wires leading through the base to said spring contacts, and a switch within the base below the supporting surface thereof serving to make or break the current through said feed wires.

5. The combination with a pressing iron having electric heating coils therein and two exposed terminals for the coils, of a stationary support to receive and hold the iron during the heating operation, a pair of contacts carried by the support and adapted to engage said terminals respectively, feed wires leading through said support to the contacts, a switch serving to complete the circuit through said wires automatically when the iron is put in place upon the support, and means to throw out said switch when the iron is lifted.
